Technical Field [0001] The present invention relates to a system and a method for providing a push service for reducing network load,

The present invention relates to a push service providing system and method, and more particularly, when a service providing device transmits a message corresponding to a notification via a push service device between a service providing device and a client. The present invention relates to a push service providing system and method that reduces a network load between a service providing device and a push service device by transmitting only one defined message and the push service device distributes the message to a plurality of clients.

With the spread of smart phones and the emergence of various applications due to the smart phone environment, the use of wireless resources has increased significantly. In particular, there are always-on applications (always-on type) connected to receive real-time push messages or push notifications from the network, such as instant messaging (IM), web, Is now rapidly increasing. Always-On type applications have a problem of causing excessive traffic and speeding up battery consumption because each is preparing to receive a push service while maintaining a connection with a service provider.

In order to solve these problems, "Apple" and "Google" do not directly connect the service provider and the client, but connect the push server through the daemon built in the client And when a service provider transmits a push message or a push notification, the central push server receives the message and transmits the message to the corresponding client.

As shown, the push service providing system 100 according to the present invention includes a plurality of service providing apparatuses 100-1 to 100-N: 100, a push service apparatus 300, and a plurality of clients 400-1 to 400- -K: 400), and shows a structure in which a plurality of service providing apparatuses 100 and a plurality of clients 400 are connected to each other via a central push service apparatus 300.

The plurality of clients 400 may include a PC, a notebook, a smartphone, a PDA, a notebook, a navigation system, a PMP, an electronic dictionary, MP3, and the like, which can be connected to the communication network 200. A plurality of clients 400 mounts a client application program that connects to the communication network 200 and transmits and receives predetermined data (in particular, push messages, push notifications, etc.).

The plurality of service providing apparatuses 100 refer to a server or a terminal for providing a service by transmitting a push message to the plurality of clients 400.

The push service apparatus 300 basically collects push messages transmitted from a plurality of service providing apparatuses 100 and delivers the push messages to the corresponding client 400. [

At this time, the push service apparatus 300 manages the interconnection of the service providing apparatus 100 and the client 400 between the plurality of service providing apparatuses 100 and the plurality of clients 400, The device 100 and the plurality of clients 400 are distributed according to the internal load. In addition, the push service apparatus 300 processes the push message transmitted from the service providing apparatus 100 to provide the push message to the corresponding client 400.

The push service apparatus 300 is implemented independently for each function, that is, it is provided with a function of interlocking between the service provider 100 and the client 400, a function of distributing load upon interworking, a function of processing push messages, The push service device 300 can be individually expanded for each function as the service providing apparatus 100 and the client 400 are increased.

3 is a detailed configuration diagram illustrating a push service apparatus according to the present invention.

The push service device 300 according to the present invention includes an SP interlocking unit 310, a control unit 320, a Client interlocking unit 330, and a load balancer 340.

The SP interworking unit 310 connects with a plurality of service providing apparatuses 100 and receives a push message to be transmitted from the plurality of service providing apparatuses 100 to the client 400. [ Here, the push message includes a message having a nature of announcement, such as new information or update information, event information.

The client interworking unit 330 connects with the plurality of clients 400 and transmits the push message received from the SP interlocking unit 310 to the plurality of clients 400.

The SP interlocking unit 310 or the client interlocking unit 330 may be provided in plural numbers according to the connection number of the service providing apparatus 100 or the client 400 connected to each of the interlocking units 310 and 330. In general, the number of terminals that can be accommodated in each of the interlocking units 310 and 330 is fixed, and thus it is possible to increase the number of terminals.

In particular, each SP linkage unit 310 and the client linkage unit 330 provides its state information to the load balancer 340 at regular intervals. The status information includes the number of subscribers (or the number of connections) connected to the SP interworking unit 310 and the client interworking unit 330, data throughput (Transaction Per Seconds (TPS)), and the like.

The load balancer 340 receives its state information from each SP interlocking unit 310 or Client interlocking unit 330, calculates load information of each interlocking unit, and stores the calculated load information in a table.

In addition, the load balancer 340 may refer to load information of a pre-stored interlocking unit when there are access requests from the plurality of service providing apparatuses 100 or the plurality of clients 400, and connect the interlocking unit to the service providing apparatus or the client, respectively. Assign. Accordingly, the load distributing unit 340 plays a role of distributing the loads of the interlocking parts 310 and 330.

The controller 320 manages the plurality of SP interlocking units 310 and the Client interlocking unit 330, and in particular, manages routing information for the Client interlocking unit 330 accessible by each client. Here, the client interlocking unit 330 that can be accessed for each client refers to a client interlocking unit in which the client maintains a connection state, and may include a client interlocking unit allocated through the load balancer 340.

Therefore, when receiving the push message from the SP interlocking unit 310, the controller 320 extracts the client interlocking unit 330 to which the corresponding client can access with the client information included in the push message, and extracts the extracted client interlocking unit 330. Send a push message.

At this time, the controller 320 controls the transmission of the push message to be transmitted to the corresponding client using a message queue. Therefore, it reduces the network load by simultaneously sending a large number of push messages, such as announcements to the client.

In more detail, the transmission control method is illustrated in FIG. 4.

4 (a) shows an example of transmitting a push message while sequentially buffering a notification message to a notification queue according to the priority of each queue.

Here, the first queue (Queue # 1), the second queue (Queue # 2), the third queue (Queue # 3), the announcement queue (Noti Queue) is a message queue that allocates and buffers the push message according to the priority It is shown. In these message queues, the priority is assumed to be the highest in the first queue (Queue # 1), followed by the second queue (Queue # 2), the third queue (Queue # 3). That is, the push message loaded in the first queue (Queue # 1) is transmitted first, and the second queue (Queue # 2) can be transmitted next with the first queue (Queue # 1) empty. The third queue Queue # 3 may be transmitted while the second queue Queue # 2 is empty.

According to this, the notification queue (Noti Queue) first processes the message while buffering three push messages existing in the first queue (Queue # 1), as shown in (b), and the first queue (Queue # 1). Buffering three push messages existing in the second queue (Queue # 2) on the push messages of The push message of the buffered second queue Queue # 2 is sequentially processed after the transmission of the push message of the first queue Queue # 1.

In addition, buffering four push messages existing in the third queue (Queue # 3) in the notification queue (Noti Queue) and buffering the third queue when the transmission of the push messages of the second queue (Queue # 2) is completed. Performs message transfer processing for the push message of (Queue # 3).

At this time, the Noti Queue checks whether the number of push messages (ie, message capacity) exceeds a threshold to reduce the load of the queue. When the threshold is exceeded, the buffering operation of the push message is stopped and a sleep function is performed.

For example, as shown in FIG. 4, if the capacity threshold of the notification queue (Noti Queue) is 9, the threshold is already exceeded when buffering the push message of the third queue (Queue # 3). At this time, the notification queue (Noti Queue) stops the buffering operation for the push message of the third queue (Queue # 3) for a predetermined time.

Therefore, the transmission control according to the present invention prevents excessive use of standby resources and reduces network load by using a message queue to transmit a plurality of push messages to a plurality of clients at a predetermined time interval without transmitting a plurality of push messages simultaneously. .

Hereinafter, a method of providing a push message using the push service system configured as described above will be described.

FIG. 5 is a flowchart illustrating a push service providing method for reducing a network load according to the present invention, and FIG. 6 is a flowchart specifically illustrating a transmission control method in the push service providing method of FIG. 5.

First, referring to FIG. 5, the service providing apparatus (SP) 100 connects to the SP interlocking unit 310 of the push service apparatus 300, delivers a push message defined as a notification, and requests transmission of the push message. (S100). Then, the SP interlocking unit 310 transmits its request to the control unit 320.

Thereafter, the control unit 320 transmits a transmission response message to the service providing apparatus 100 through the SP interlocking unit 310 (S110).

In addition, the controller 320 inquires a list of clients to transmit the push message (S120).

Thereafter, the controller 320 performs transmission control while buffering the push message in the message queue based on the inquired client list (S130). A detailed method of the transmission control is shown in FIG.

That is, a push message for each client is allocated to the message queue (S131), and the allocated push message is sequentially buffered according to the priority of the message queue (S133). Here, the push message assigned to the message queue is one and the same message, but the unit of buffering the message queue corresponds to the client. That is, the push message is buffered in the message queue for each client to be transmitted.

When buffering, the capacity threshold of the message queue is checked (S135). If the capacity threshold is less than or equal to the push queue (S131), if the capacity threshold is exceeded, sleep (sleep) to stop the buffering operation of the message queue for a while Perform a function (S137).

Thereafter, the control unit 320 transmits the buffered push message to the corresponding client interlocking unit 330 according to the transmission control, and transmits the distributed message by transmitting the received client interlocking unit 330 to the client (S140).

At this time, if there are a plurality of clients, the transmission is performed while buffering each client at a predetermined time interval.

Thereafter, the controller 320 checks whether the transmission of the push message has been completed (S150), and if so, discards the corresponding push message (S160). If not, the control unit 320 transmits the message through transmission control again (S130, S140). ).

As described above, when the push message corresponding to the announcement is transmitted between the message service providing device and the client through the push service device, the service providing device transmits only one push message defined between the push service devices and the push service device is used. By buffering one push message in a message queue by a plurality of clients, push messages are distributed and transmitted at regular intervals.

The foregoing description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the spirit of the present invention. Accordingly, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention. The scope of the present invention should be construed according to the following claims, and all the techniques within the scope of equivalents should be construed as being included in the scope of the present invention.

In the conventional system for providing a push service, when the number of connection between the service provider and the client increases rapidly, an excessive load is generated due to the bias of the terminal to be accommodated in the push server. When sending a message corresponding to an announcement, the service providing device transmits only one message defined between the push service devices and the push service device distributes the message to a plurality of clients, thereby reducing the network load between the service providing device and the push service device. It has a reduced effect. In this respect, as the conventional push server is overcome, it is not only the use of the related technology, but also the possibility of construction and operation of the applicable server is sufficient and it is practically possible to carry out clearly, so that a useful invention to be.
